'function' must return a value
The given function did not return a value.
Only functions with a return type of void can use the return command without an accompanying return value.
An undefined value will be returned when this function is called.
This warning is automatically promoted to an error. If you wish to modify this behavior, use #pragma warning. For example, to make C4716 into a level 4 warning issue,
#pragma warning(4:4716)
in your source code file.
The following sample generates C4716:
int test(void) { // uncomment the following line to resolve // return 0; } void main() { }
